FLIGHT COLLISION AVOIDANCE USING GPS BASED INTELLIGENT BEACON SYSTEM

project center in Tirunelveli 

Collision in Aviation is an unexpected accident in which two or more flights come into unplanned contact during flight. Owing to the relatively high velocities involved and the likelihood of subsequent impact with the ground or sea, very severe damage or the total destruction of at least one of the aircraft involved usually results. The potential for these collisions is increased by deviations from flight paths and the lack of collision-avoidance systems. Although a rare occurrence in general due to the vastness of open space available, collisions often happen near or at airports due to communication towers or any ancient tall buildings. The project is proposing a collision avoidance system for the aviation system. The Global position system (GPS) is responsible to locate the longitude and latitude of the accident zones like communication tower or tall buildings nearby. The embedded controller is casting as a brain for the proposed beacon system inside the flight. The beacon system can intimate the pilot while crossing the dangerous zone. The system also able to recognize the flight-to-flight collision with the help of sensors array fixed on the each flight body. This arrangement can alert the beacon system if there are any symptoms detected for collision. This intelligent beacon system is alerting the pilot by means of voice or alarm.  Thus the proposed collision avoidance is profitable vigilant system for avoiding the unnecessary flight collisions.

Children often fall down in the bore well which have been left uncovered and get trapped. The rescuing of this trapped child is not only difficult but also risky. A small delay in the rescue can cost the child his or her life. To lift the child out the narrow confines of the bore wells is also not very easy. The child who has suffered the trauma of the fall and is confined to a small area where, with a passage of time the supply of oxygen is also reduces. This project genesis a robotic based child recuing in particular for the latter accidents. Robots can only offer a solution for bore well rescue because it is fast, Economical and safe. Moreover, it has the facility to monitor the trapped child and provide a supporting platform to lift up the child. Borehole robot consists of 3 wheels with rubber grip for which motors are connected and these wheels have spring suspension also. So that, the wheels will exact fit to the walls of the hole which make the robot to travel down without any sliding and also this robot consists an arm which is used to pick up the child from the borehole. This aids to recover the child from the bore well without any danger of the victim. The sensor systems are interfaced with the brain of the robot called “Arduino”. A camera along with an LED light is used to visualize the victim as well as it helps to operate the system by control unit. The robot Hand movement is used to adjust the child position while lifting. The arm movement of the robot is controlled by DC motor. Once child is perfectly picked by robot, DC motor is used to lift up the child from borewell. The ZigBee plays a vital role of data transferring between the victim in borewell and the recovery team in earth surface with monitor.

LAST-METER SMART GRID EMBEDDED IN AN INTERNET-OF-THINGS PLATFORM

project center in Tirunelveli 

The customer domain of the smart grid naturally blends with smart home and smart building systems, but typical proposed approaches are “distributor-centric” rather than “customer-centric,” undermining user acceptance, and are often poorly scalable. To solve this problem, we propose a detailed architecture and an implementation of a “last-meter” smart grid—the portion of the smart grid on customer premises—embedded in an internet-of-things (IoT) platform. Our approach has four aspects of novelty and advantages with respect to the state of the art: 1) seamless integration of smart grid with smart home applications in the same infrastructure; 2) data gathering from heterogeneous sensor communication protocols; 3) secure and customized data access; and 4) univocal sensor and actuator mapping to a common abstraction layer on which additional concurrent applications can be built. A demonstrator has been built and tested with purposely-developed ZigBee smart meters and gateways, a distributed IoT server, and a flexible user interface.

project center in Tirunelveli 

This project proposes a load oscillation monitoring technique “load restoration method” based on wireless WAMs. An electrical power system network is very sensitive to load changes and it may result into complicate power delivery to connected loads. The available two solutions for this abrupt load changes are load restoration or rescheduling and load shedding. This project proposes a novel technique called Load restoration Method for power system oscillation monitoring based on Wide Area Monitoring (WAM). It is considered to monitor the load oscillations among the main grid and the connected substations with the help of WAMs. This wireless communication system is effectively monitoring the load levels of each substation and transferring the collected data into the substation level control rooms. The load restoration is done depending upon the available energy on the grid side and load shedding may also applicable if the load limitations exceeds. The great advantages of the proposed work is that the work is focusing the large amount of area without any physical medium for communicate and hence the HV side load monitoring & load restoration is possible.

A HYBRID BI-DIRECTIONAL WIRELESS EV CHARGING SYSTEM TOLERANT TO PAD MISALIGNMENT

project center in trichy

              Electric vehicles (EVs) are becoming increasingly popular as a means of future transport for sustainable living. However, wireless charging of EVs poses a number of challenges related to interoperability, safety, pad misalignment etc. In particular, pad-misalignments invariably cause changes in system parameters which in turn lead to increase in losses as well as reduction in power throughput, making the charging process long and inefficient. Consequently, wireless charging systems that are less sensitive to pad-misalignments have become preferable. This paper, therefore, presents a hybrid Wireless Power Transfer (WPT) system that charges EVs at constant rate despite large misalignments between charging pads. The proposed charging system uses a combination of two different resonant networks to realize a constant and efficient charging process. A mathematical model is also developed, showing as to how the two resonant networks can be combined to compensate for pad-misalignments. To demonstrate the validity of the proposed concept as well as the accuracy of the mathematical model, theoretical performance is compared with both simulations and experimental results of a prototype 3.3 kW hybrid bidirectional WPT system. Results clearly indicate that the proposed hybrid WPT system is efficient and offers a constant charging profile over a wide range of spatial (3D) pad-misalignments.

POWER ROUTING FOR CASCADED H-BRIDGE CONVERTERS

project center in trichy

Modular power converters are expected to play a major role in medium and high voltage/power applications. Normally, each module processes the same amount of power, however this does not take into consideration that different modules can have a different remaining useful lifetime. This paper proposes the concept of power routing for cascaded H-bridge (CHB) converters, with the purpose of delaying the failure of the system. A third-harmonic injection into the duty cycles allows extending the imbalance capability of the structure, keeping the CHB operational even if some power paths are completely unloaded. Analytic investigation in conjunction with simulation and experimental measurements demonstrate the power routing by means of the proposed method.

TRAJECTORY OPTIMIZATION FOR LOSS MINIMIZATION IN INDUCTION MOTOR FED ELEVATOR SYSTEMS

project center in trichy

 This paper presents a novel loss minimization technique for Induction Motor Driven Elevator Systems (IMDES) to determine an energy optimum velocity pattern. The objective function consists of a differential equation relating total power losses in the induction motor to its rotor speed. The constraints are provided in terms of velocity and acceleration governed by passenger comfort. Since, the velocity and acceleration are state variables, Pontryagin’s Minimum Principle is used to determine the most optimum trajectory by forming an appropriate Hamiltonian function. Boundary conditions are specified and used to obtain the coefficients of the rotor speed equation. As the velocity is optimized, the total travel time is not fixed and treated as a variable. A fixed-point iterative procedure is used to estimate the travel time. Additional loss minimization is incorporated by optimizing the machine flux for the constrained portion of the velocity pattern. An algorithm for implementing the optimization scheme is explained in detail. The theoretical claims are supported with analytical and experimental results. Proposed technique is developed for IMDES, but it can be easily adapted to other drive applications as well.

NEW SWITCHING STRATEGY FOR SINGLE MODE OPERATION OF A SINGLE-STAGE BUCK-BOOST INVERTER

project center in trichy

Generally, single-stage buck-boost inverters consist of distinct circuits operating individually in buck/boost or positive/ negative modes, the latter definitely leading to crossover distortion in the output current. This paper proposes a switching strategy that changes the bi-modal operation of a single stage buck-boost topology to a single mode inverter (SMI). This is due to the consequent voltage gain which ensures that the output voltage polarity, apart from its magnitude, is an exclusive function of the duty ratio. Operational principle and salient hardware design are explained with the help of equivalent circuits. Details about the dynamic model are presented, based on which controller design is carried out for both stand-alone and grid-connected operation. Experimental results obtained from a 300 W, 110 V laboratory prototype are presented to validate the performance of the proposed switching strategy.

MULTI-INPUT SWITCHED-CAPACITOR MULTILEVEL INVERTER FOR HIGH-FREQUENCY AC POWER DISTRIBUTION

project center in trichy

This paper proposes a switched-capacitor multilevel inverter for high frequency AC power distribution systems. The proposed topology produces a staircase waveform with higher number of output levels employing fewer components compared to several existing switched capacitor multilevel inverters in the literature. This topology is beneficial where asymmetric DC voltage sources are available e.g. incase of renewable energy farms based AC microgrids and modern electric vehicles. Utilizing the available DC sources as inputs for a single inverter solves the major problem of connecting several inverters in parallel. Additionally, the need to stack voltage sources, like batteries or super-capacitors, in series which demand charge equalization algorithms, are eliminated as the voltage sources employed share a common ground. The inverter inherently solves the problem of capacitor voltage balancing as each capacitor is charged to the value equal to one of input voltage every cycle. State analysis, losses and the selection of capacitance are examined. Simulation and experimental results at different distribution frequencies, power levels and output harmonic content are provided to demonstrate the feasibility of the proposed multilevel inverter topology.
